GCC 4.6 performance regressions

2011-02-08 Thread Tony Poppleton
Hi, The following article has a fairly comprehensive set of benchmarks run against all the current stable releases of GCC as well as 4.6.0. http://www.phoronix.com/scan.php?page=articleitem=intel_avx_gccnum=1 There are some great results for 4.6.0 in there, which is very good news

While I appreciate Phoronix as a booster site, their benchmarking practice often seems very dodgy; I'd take the results with a large grain of salt The main reason I posted the link in the first place was because it was reflecting my own emperical evidence for the application I am working

Thanks for the feedback. Moving the test case into an attachment won't be useful. What would be useful is recasting the test case into a form which can be used in the gcc testsuite, if possible Whilst I would like to be able to submit new test cases as I go, as you (Ian) pointed out this may

2011-01-06 Thread Tony Poppleton
Hi, I would like to help with some gcc bug triage, and have a few questions about doing so. 1. My plan is to start testing bugs against the latest stable build (4.5.2), on an Intel x86-64 architecture (possibly also testing 32 bit bugs). My main focus will be on missed-optimizations, although I
